Collimator R&d Collimator R&d

The importance of collimator R&D with test beam facilities is demonstrated with the example of ILC collimator studies at SLAC End Station A. Related LHC collimator aspects and longer term plans are addressed. Presented at IDTB07, ILC Detector Test Beam workshop, Fermilab, USA, 2007.

(r, R+1)-factorizations of (d, D+1)-graphs

A (d, d + 1)-graph is a graph whose vertices all have degrees in the set {d, d + 1}. Such a graph is semiregular. An (r, r + 1)-factorization of a graph G is a decomposition of G into (r, r + 1)-factors. For d-regular simple graphs G we say for which x and r G must have an (r, r + 1)-factorization with exactly x (r, r + 1)-factors. We give similar results for (d, d + 1)-simple graphs and for (d...

Assessing Agent Applications - r&D vs. R&d

This paper discusses the discrepancy between the stated aims of agent research with regard to agent applications, and the reality as found in many (general) agent conferences. After analysing this discrepancy by looking at the distribution of application papers at past AAMAS conferences, we analyse relevant stakeholders for agent application papers and provide suggestions for them. The aim of t...

Ilc Rf System R&d * Ilc Rf System R&d*

The ILC Linac Group at SLAC is actively pursuing a broad range of R&D to improve the reliability and reduce the cost of the L-band (1.3 GHz) rf system. Current activities include the development of a Marx-style modulator and a 10 MW sheet-beam klystron, construction of an rf distribution system with adjustable power tap-offs and custom hybrids, tests of cavity coupler components to understand r...
